1. In a turbo jet engine, the momentum of the gases leaving the nozzle produces the propulsive force. The enthalpy and velocity of the gases at the nozzle entrance are 1200 kJ/kg and 200 m/s respectively. The enthalpy of the gas at exit is 900 kJ/kg. If the heat loss from the nozzle is negligible, determine the velocity of the gas jet at exit from the nozzle. 2. For question 1, if the diameter of the nozzle at exit is...

A firefighter mounts the nozzle of his fire hose a distance 36.9 m away from the edge of a burning building so that it sprays from ground level at a 45° angle above the horizontal. After quenching a hotspot at a height of 9.45 m, the firefighter adjusts the nozzle diameter so that the water hits the building at a height of 17.1 m. By what factor was the nozzle diameter changed? Assume that the flow rate of water through...
